Singapore’s No.6 Wheelset: An Asian Upstart’s Ultralight Design

In a carbon wheel market long dominated by European and American brands, Singapore’s No.6 (Number 6) has broken through with extreme lightweight engineering and a refined Asian design aesthetic. This young brand is proving that a top-tier carbon wheelset doesn’t have to come from Utah or Italy.

Brand Story

No.6 was founded in Singapore, and the name refers to the country’s ranking among the world’s smallest nations — sixth. “Building the lightest wheels in one of the smallest countries” is the brand’s core philosophy. The founding team comes from an aerospace and carbon-fiber engineering background, and they’ve applied aerospace-grade carbon fiber techniques to bicycle wheels.

Product Line

No.6 currently offers several carbon wheelset series:

Series	Rim Depth	Weight	Positioning	Price (NT$)
Dash 40	40mm	1,240g	All-round lightweight	55,000-68,000
Dash 50	50mm	1,310g	Aero lightweight	55,000-68,000
Dash 60	60mm	1,380g	Aero flagship	58,000-72,000

Dash 50 Full Specifications

Item	Spec

External rim width	28mm
Internal rim width	21mm
Weight (front+rear)	1,310g (disc brake version)
Hub	DT Swiss 240 EXP or Industry Nine
Spokes	Sapim CX-Ray
Spoke count	20 front / 24 rear
Tire compatibility	Tubeless Ready (hooked rim)

The Engineering Behind the Weight Savings

Aerospace-Grade Carbon Fiber

No.6 uses a mixed layup of Toray T800 and T1000 carbon fiber, applying high-modulus carbon fiber in critical load-bearing zones and lighter standard-modulus carbon fiber elsewhere. This “selective reinforcement” strategy is standard practice in aerospace structural design.

Finite Element Analysis

Every rim cross-section is optimized through FEA (Finite Element Analysis), thinning the wall thickness to its minimum while still meeting UCI strength standards. This precise engineering analysis lets No.6 achieve extremely low weight even without resorting to carbon spokes.

Quality Control

While the rims are manufactured at factories in Asia, No.6 performs final assembly and quality inspection in Singapore. Every wheelset undergoes ultrasonic testing and pressure testing to ensure aerospace-grade quality.

Hub Options Strategy

No.6 offers two hub choices:

DT Swiss 240 EXP

• The most reliable option
• Ratchet EXP upgradeable to 54T
• Excellent global service network
• Lower price point

Industry Nine Hydra

• 690 points of engagement, 0.52-degree engagement angle
• The fastest engagement response in the industry
• The brand’s signature buzzing freehub sound
• Handbuilt in the USA
• Higher price point (roughly NT$8,000-12,000 premium)

Real-World Riding Experience

Sense of Lightness

At 1,310g paired with a 50mm rim depth, the Dash 50 delivers a surprisingly light feel on climbs. As a spoked (non-carbon-spoke) wheelset, this weight sits at the top of its class among carbon wheels.

Aerodynamic Efficiency

The 50mm rim depth combined with a 28mm external width offers solid aero advantages when cruising on flats. Developed in Singapore’s flat terrain, the Dash 50’s aero shape is optimized for the 35-45 km/h speed range.

Stiffness Balance

The extremely low rim weight means less carbon fiber material overall, which could mean lower stiffness compared to heavier competitors. However, No.6’s FEA optimization strikes a good balance between weight savings and stiffness — for most Asian riders under 70 kg, this stiffness level is more than adequate.

Built for Asian Riders

No.6’s design specifically accounts for the body types and riding conditions of Asian cyclists:

• Optimized for riders in the 55-75 kg range
• Material choices that account for Asia’s humid climate
• Heat-dissipation design suited to Asia’s hot riding environment

Comparison with Other Lightweight Carbon Wheels

Wheelset	Rim Depth	Weight	Spokes	Price (NT$)
No.6 Dash 50	50mm	1,310g	Steel	55,000-68,000
CADEX 50 Ultra	50mm	1,198g	Carbon	95,000-110,000
Winspace HYPER 50	50mm	1,330g	Steel	25,000-38,000
Zipp 303 FC	40mm	1,355g	Steel	45,000-55,000

Pros and Cons

Pros

• Top-tier lightweight among steel-spoked wheelsets (1,310g @ 50mm)
• Aerospace-grade quality control
• Premium DT Swiss / Industry Nine hub options
• An Asian brand with cultural familiarity for the region
• Design optimized for Asian riders
• Good compatibility with hooked-rim tire setups

Cons

• Short brand history; long-term durability not yet proven
• Limited purchasing channels in Taiwan
• Not the cheapest option in its class
• Internal rim width of 21mm is somewhat narrow
• Brand recognition trails major European and American names
• Heavier riders should pay attention to stiffness limits

Buying Advice for Taiwan Riders

Purchase Channels

• No.6’s official website
• Singapore bike shops (international shipping available)
• Occasional group buys within Taiwan’s cycling community

Who Is It For?

• Asian riders in the 55-75 kg range
• Riders chasing a lightweight build without stretching to carbon-spoke pricing
• Cyclists who want to support an Asian brand
• Buyers who value rigorous quality control

Conclusion

No.6 represents a new wave of Asian carbon wheel brands — no longer competing on the low-cost, contract-manufacturing model long associated with the region, but instead positioning itself in the mid-to-high-end market with aerospace-grade engineering and refined design. The Dash 50’s 1,310g steel-spoke weight proves that an Asian brand can hit top-tier carbon manufacturing standards. For Asian riders chasing lightweight performance, No.6 is a brand well worth serious consideration.
